joist question

Staple away. This is done all the time, often for more than one wire.

Take a look at your ceilings. All that sheetrock is attached to the joists with nails or screws every 8".

As Mr. Pawlowsky says, staples, nails and screws are not going to reduce the structural capacity of the joists. If you plan to notch or drill holes in the joists, ask for advice. T

Hmmm, Nails, staples, even some holes it'll take it without any concern.

My personal opinion, would use clamps designed for round coax cable, normally used with cable TV. These can be nailed or screwed. Use appropriate nails if you may change your mind in the routing, will pop out easily with a claw hammer. Dave

No problem with this but.. make sure the wires aren't near the top or bottom of the joist - keep them in the middle vertically - at least the length of a floorboard nail away from the top!

No, this won't cause any serious reduction in joist capacity.

I wondered this myself. The other posters don't have a concern. But if you have existing wiring going through the joists like I did, you might try and follow it.

I also tried to use the cross bracing on the joists, rather than the joists, when I ran cable perpindicular to the joists.

Will be using those clamps.

Thanks to all those who responded.

Much obliged

Your furnace might blow up. You better contact a pro.
